Question

如何在我的Widget中有一个图像，然后当它点击时更改为另一个图像？它是一个只有一个ImageButton的小部件，但是我不知道在这之后去哪里，我知道所有关于待定意图等等，但这在这里没有用，除非我遗漏了什么......这是我的onUpdate

public void onUpdate(Context context,AppWidgetManager appWidgetManager,int[] appWidgetIds){
   RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget);
   PendingIntent onPendingIntent = PendingIntent.getService(context, 0, new Intent(context, widgetService.class), 0);
   remoteViews.setOnClickPendingIntent(R.id.ImageButton01, onPendingIntent);
   appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
 }

Answer 1

我认为这就是你要找的东西

 /* get the handle on your widget*/
 RemoteViews views = new RemoteViews(getPackageName(), R.layout.your_widget_layout);
 /* replace the image */
 views.setBitmap(R.id.id_of_your_imageview, "setImageBitmap", yourBitmap);

 /* update your widget */
 ComponentName thisWidget = new ComponentName(this, YourWidget.class);
 AppWidgetManager manager = AppWidgetManager.getInstance(this);
 manager.updateAppWidget(thisWidget, updateViews);

试试这个：

public void onUpdate(Context context,AppWidgetManager appWidgetManager,int[] appWidgetIds){
   RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget);
   PendingIntent onPendingIntent = PendingIntent.getService(context, 0, new Intent(context, widgetService.class), 0);

   remoteViews.setOnClickPendingIntent(R.layout.widget2, onPendingIntent);
                                      **add widgetON.xml*

为“widgetON”图像设置单独的.xml布局。（WIDGET2）然后，你必须弄乱remoteViews来区分ON / OFF视图

我想。：D
